WebVerified by Toppr. Correct option is C) In the normal ECG, the QS wave shows the negative deflection. In the QRS complex, the first negative deflection is shown by the Q wave which is followed by the positive deflection of R wave. Again, the R wave is followed by the negative deflection of S wave. Therefore, the correct option is C.
